Why WCAG Contrast Matters
Accessibility is no longer optional in web design. The Web Content Accessibility Guidelines (WCAG) require specific contrast ratios between text and its background to ensure readability for users with visual impairments.
Understanding Ratios
A contrast ratio of 4.5:1 is required for standard text (AA level). Large text requires at least a 3.0:1 ratio. The AAA standard (the strictest level) requires 7.0:1 for normal text and 4.5:1 for large text.
